Product analysis

59 out of 100

St. John's Wort Flower & Leaf 300 mg has uncertain mood benefits because the freeze-dried herb does not match the standardized extracts behind the supporting evidence.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality40

The freeze-dried preparation is named, but its ingredient quality cannot be firmly compared. That description does not establish equivalence to a standardized extract.

Ingredient Transparency100

The herb amount and preparation are both clearly stated. Those details help distinguish it from differently prepared extracts.

Value For Money40

Value remains uncertain for this preparation. Reliable serving-cost comparisons are unavailable.

Customer Satisfaction69

Customer feedback is positive. The modest review base gives a useful but limited picture of satisfaction.

Product Focus54

Mood support is the narrow intended use, but the benefit from this preparation is unclear. Findings from standardized extracts do not automatically apply to freeze-dried flower and leaf material.

Whether this freeze-dried St. John's wort improves everyday mood is unclear. Benefits associated with particular standardized extracts for diagnosed depression don't transfer automatically to flower and leaf material. The declared amount tells you how much herb is present, but it doesn't identify an interchangeable extract or establish that this preparation will have the same effects.
